Resolution and reproducibility of measures of the diameter of small collagen fibrils by transmission electron microscopy-application to the rabbit corneal stroma

The results indicate that different average values for measures of fibril diameter of small collagen fibrils can easily be obtained according to the final magnification used and the number of fibrils measured, and that the overall averages can depend on whether the data sets are averaged or pooled. These aspects of the morphometry of small collagen fibrils therefore need to be carefully specified.
